Workers’ compensation benefits generally do not count toward retirement benefits. The weekly checks replace part of your lost wages, but they are not wages, salary, or earned income under the rules that govern pensions, 401(k) plans, IRAs, and Social Security. A long stretch on workers’ comp can quietly shrink what you retire with, even while the benefit payments keep arriving on time.
How a Pension Handles Time on Workers’ Comp
Defined benefit pensions calculate your payout from two numbers: your salary history and your years of credited service. Most plan documents define “compensation” as wages, bonuses, and similar payments from the employer for services rendered. Workers’ comp sits outside that definition, so months or years on benefits typically don’t feed the pension formula.
The damage can compound. If your plan uses a final-average-pay formula, a workers’ comp stretch late in your career can drag that average down by replacing what would have been your highest-earning years. You may also lose service credits for the time you were out, which cuts directly into the multiplier used to compute your monthly benefit. Whether any of that time counts is entirely a plan-document question, which is why your Summary Plan Description is the first thing to read.
Vesting and Breaks in Service
Even when workers’ comp time doesn’t build your benefit, it can still affect your vesting. Federal regulations generally credit an “hour of service” for any hour you’re paid or entitled to payment, including periods of disability. The regulations then carve out an exception: hours paid under a plan maintained solely to comply with workers’ compensation or disability insurance laws are not required to be credited toward vesting service.1eCFR. Part 2530 Rules and Regulations for Minimum Standards for Employee Pension Benefit Plans In plain terms, the pension plan isn’t legally obligated to count your workers’ comp period as service time.
You generally won’t hit a formal “break in service” unless you complete fewer than 500 hours of service in the plan’s computation period.2Office of the Law Revision Counsel. 29 U.S. Code 1053 – Minimum Vesting Standards An injury midway through a plan year, after you’ve already logged enough hours, usually leaves your vesting intact for that year. Risk shows up when the absence spans a full computation period.
One protection is worth knowing. If your employer designates the workers’ comp absence as FMLA leave, which it can do when the injury is a serious health condition, the unpaid FMLA period cannot be treated as a break in service for vesting or eligibility.3eCFR. Subpart B Employee Leave Entitlements Under the Family and Medical Leave Act FMLA caps at 12 weeks a year, so it won’t cover a long absence, but it bridges the early months.
401(k) and IRA Contributions While on Comp
The Internal Revenue Code limits tax-advantaged retirement contributions to “compensation” from an employer or “earned income” from self-employment. Workers’ comp is neither. You can’t make elective deferrals into your 401(k) out of workers’ comp checks, and your employer has no wages from which to withhold contributions. The 2026 401(k) elective deferral limit is $24,500, but the ceiling is beside the point when you have no qualifying compensation to contribute against.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
The same earned-income requirement applies to IRAs. Under 26 U.S.C. § 219, you need “compensation” to fund a traditional or Roth IRA.5Office of the Law Revision Counsel. 26 U.S. Code 219 – Retirement Savings If workers’ comp is your only income for the year, your IRA contribution limit is zero. One workaround exists for married couples: if your spouse has earned income, a spousal IRA lets the working spouse fund an IRA on your behalf up to the annual limit.
When the Employer Can Keep Contributing
Some employers voluntarily continue matching or profit-sharing contributions during a disability absence, and the tax code provides a specific mechanism for it. For a permanently and totally disabled participant who isn’t highly compensated, the employer can elect to treat the person as if they were still earning their pre-disability pay for purposes of defined contribution plan limits.6Office of the Law Revision Counsel. 26 USC 415 – Limitations on Benefits and Contributions Under Qualified Plans Any contributions made on this basis must vest immediately. It’s a generous option, and it’s optional. Ask HR whether your employer has adopted it.
Handling an Outstanding 401(k) Loan
If you had a 401(k) loan when the leave started, you may not have income to make the required payments. IRS rules let a plan suspend loan repayments during a leave of absence for up to one year.7Internal Revenue Service. Retirement Plans FAQs Regarding Loans When you return, you make up the missed payments through larger installments or a lump sum so the loan still finishes inside the original five-year term. If the leave stretches past a year and the plan offers no further suspension, missed payments can trigger a deemed distribution, meaning taxes and possibly a 10% early withdrawal penalty on the outstanding balance.
Social Security and the 80% Cap
Collecting workers’ comp and Social Security Disability Insurance at the same time triggers one of the trickiest rules in benefits planning. Federal law caps the combined SSDI and workers’ comp payments at 80% of your “average current earnings” before the disability began.8Office of the Law Revision Counsel. 42 USC 424a – Reduction of Disability Benefits If the combined total goes over, the Social Security Administration reduces your SSDI to bring you back under the cap.9Social Security Administration. How Workers’ Compensation and Other Disability Payments May Affect Your Benefits
The offset ends at full retirement age, which is 67 for anyone born in 1960 or later. At that point, SSDI converts to regular Social Security retirement benefits and the workers’ comp offset falls away.10Social Security Administration. Retirement Age Calculator
Reverse Offset States
About 15 states flip the formula. Instead of Social Security reducing SSDI, these “reverse offset” states reduce the workers’ compensation benefit to account for the concurrent SSDI payment.11SSA – POMS. DI 52105.001 – Reverse Offset Plans Your full SSDI stays intact and your workers’ comp shrinks instead. Which side gets cut affects your tax picture and your total monthly income, so a call to your workers’ comp insurer or a look at your state’s statute is worthwhile.
Lump-Sum Settlements
Settling your workers’ comp claim for a lump sum doesn’t eliminate the offset. SSA prorates the settlement into a monthly equivalent and applies the same 80% cap it would apply to periodic payments. If the settlement doesn’t specify a time period, SSA divides the gross lump sum by your remaining life expectancy to get a monthly rate.12SSA – POMS. Complex Lump Sum (LS) Awards and Settlements A bigger settlement produces a higher imputed monthly rate, which can raise the SSDI offset for years.
Medical expenses and attorney fees connected to the workers’ comp claim can be excluded from the offset calculation.13Office of the Inspector General, Social Security Administration. Workers’ Compensation Lump-sum Settlements The exclusion lowers the imputed monthly rate. Make sure the settlement agreement itemizes these costs, because SSA needs documentation to apply the exclusion.
Federal Employees Have to Choose
Federal workers face a sharper version of the same problem. If you qualify for both a FERS disability retirement annuity and continuing workers’ compensation from the Office of Workers’ Compensation Programs, you must pick one. Federal law prohibits collecting both for the same period.14Office of the Law Revision Counsel. 5 U.S. Code 8337 – Disability Retirement The exception is a “scheduled award,” which compensates for loss or loss of use of a specific body part and can run alongside the annuity.
The choice isn’t obvious. OWCP benefits are tax-free, replace roughly two-thirds of your salary (three-quarters with dependents), and continue as long as the disability does. FERS disability retirement pays 60% of your high-three average salary the first year and 40% after that, is taxable, and counts toward federal retirement service. Many injured federal employees take OWCP for the higher tax-free payment, but those years then don’t add to FERS service credit. It is one of the bigger long-term trade-offs in federal benefits.
Tax Angles That Affect Your Retirement Picture
Workers’ compensation itself is exempt from federal income tax. The Internal Revenue Code excludes amounts received under workers’ compensation acts as compensation for personal injury or sickness.15Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness That’s clean when workers’ comp is your only income. It gets messier when other retirement-related money enters the picture.
If your SSDI is reduced by the workers’ comp offset, the offset amount is treated as a Social Security benefit for tax purposes. Whether tax is actually owed depends on your total income. Social Security becomes partially taxable when combined income exceeds $25,000 for single filers or $32,000 for married couples filing jointly.16Internal Revenue Service. 2025 Publication 915 The offset amount is added to your Social Security figure on Form SSA-1099, which can push you over those thresholds even though the money came in as workers’ comp.
Distributions from a 401(k) or traditional IRA taken during a workers’ comp period are fully taxable as ordinary income. The workers’ comp exemption doesn’t shield any other source. Drawing from several accounts at once, especially with taxable SSDI in the mix, can move you into a higher bracket than you’d expect. Timing withdrawals through the overlap period is worth some planning.
What to Read in Your Plan Document
ERISA sets minimum standards for private-sector retirement plans and requires employers to spell out plan terms in a Summary Plan Description.17U.S. Department of Labor. Employee Retirement Income Security Act (ERISA) What ERISA does not do is force your employer to keep making retirement contributions while you’re on workers’ comp.18U.S. Department of Labor. FAQs About Retirement Plans and ERISA Whether contributions continue, whether your time out counts toward vesting, and whether you accrue service credits during the absence are all governed by the plan document itself. If HR can’t give you a clear answer, request the plan document and look at three sections: “hours of service,” “compensation,” and “leave of absence.” Those will tell you almost everything you need to know about how workers’ comp will affect your retirement.
